Answer:
Step-by-step explanation:
8d+2d+6d+9-6d = 0
First, combine like terms, so it would become;
10d+9 = 0
Then, separate anything without a variable;
10d = -9
Then you divide;
d= -0.9
15% of x = 21
Set up proportions.
15/100 = 21/x
Cross multiply the numbers (15 by x, 21 by 100).
Divide 2100 by 15x to get x.
2100/15 = 140
X is 140.
Answer:
BD = 21 units
Step-by-step explanation:
By applying mean ratio theorem in the given triangle ABC,

AD × CD = BD²
21 × 21 = BD²
BD² = (21)²
BD = 21
Therefore, measure of segment BD is 21 units.
